Satellite communicators & SOS (not phones). inReach, Spot, etc

[ultraflight]

Has anyone here actually used an emergency satellite communicator (not a satphone) in a real emergency to summon help?
if so, what device did you use, and how was the response and the experience in them dealing with the emergency?
